How P-Value Works

The p-value measures the probability of obtaining results at least as extreme as observed, assuming the null hypothesis is true. A small p-value (typically < 0.05) suggests the result is statistically significant.

Steps

Enter the test statistic (Z-score, t-score, or F-statistic).
Select the test type (one-tailed or two-tailed).
View the p-value and whether the result is significant at common alpha levels.
